The results show that at the moment of purchase, the cost of the electric vehicle is actually higher than the fossil fuel-engine vehicle, but starting in the second year, because of the high cost of fuel, running an electric vehicle costs considerably less.

Factors lowering the break-even point of electric cars:

High performance of electric motors: the separate excitation electric engines used in Alke' electric vehicles have a theoretical energy output of 85%, and this is what began to make a really noteworthy result possible.

Energy recovery while braking. Whilst braking, the 6 kW (17,5 kW at its peak) separate excitation electric engines of the Alkè ATX vehicles transform themselves into dynamos and generate energy. This energy, which would otherwise be lost through the heat of the braking action, is sent to the traction batteries. The result is that the electric vehicle uses 30% less energy, the battery lasts longer and the general energy performance is higher.

Low running and maintenance costs. In general, the maintenance costs of electric vehicles is much lower than that of an equivalent diesel or petrol vehicle.

Break-even point of electric vehicles: the typical curve of the break-even point (bep) graph of electric cars is a step graph, as evidenced by the yellow line in the graph to the left. The cost line is almost horizontal as the amount of electrical energy used is very low. Energy waste has been reduced to a minimum, and the energy used by a set of batteries during an entire day’s work is the equivalent of 1.1 litres of petrol. With this small amount of energy one can transport up to 600 kg for from 70 to 90 km – a cost efficiency result that one could never obtain using a standard petrol-run vehicle. The step upwards in the graph represents the cost of the batteries, which should be replaced every 4 years or so.
